The Great Admiral Yi Sun Shin Festival, which is held in Asan, celebrates one of Korea’s most famous war heroes ‘Yi Sun-shin”, who defeated the Japanese in a momentous naval battle around 460 years ago. The festival takes place in the period around the Admiral’s birth date on April 28 in order to commemorate his achievements. Events at the festival will include a reenactment of the parade when Yi Sun-shin took his sailors off to war and displays featuring detailed reproductions of the famous turtle-shaped ships (Geobukseon, “Turtle Ship”), which were used in battle.
